Specification of Letters Patent.

Application filed July 6, 1844. Serial No. 849 131.

To all whom it m (17 concern Be it known that We, .l'mrns T. HAMIL'roN and Ceramics (l. lvlcllflcniyicx. citizens of the United States, residing at Ellisville, in the county of Jones and State of Mississippi,

have invented certain new and useful linprovements in llailwayfiwitches; and we do dccla re the following to be a full, clear, and exact description of the invention, such will enable others skilled in the art to whi 'ch is appertains to make and use the same.

filur invention relates to improvements in railway switches and has for its primary obect to provide simple and efficient means whereby the usual frog may be dispensed with.

. A secondary object of the invention is to construct the device in such a manner as to allow both the main line and siding to have practically solid rails.

In carrying out these objects, we provide a pivoted. rail section which is adapted to bridge a gap in one rail of the in. line or in one rail of: the siding as the case may be.

A "n-ther object of the invention is to provide simple and ellicient means whereby said pivot/ed rail section is held against tilting.

A still further object is to provide means, carried by said pivoted rail section, for preventing injury to a dragging brake beam.

lVith these objects in view, our invention resides in certain novel features of construclion and combination herein described and claimed and shown in the drawings wherein Figure l is a plan view of a railway switch constructed in accordance With our invention, the switch being closed; Fig. 2 is a similar view vith the switch open; Fig. 3 is a transverse section taken along the plane of the line 3-43 of Fig. 1; Fig. 4 is a have invented certain new and useful linsimilar view taken upon the line L lof Fig. l: and Fig. 5 is a detail perspective view or a portion of the pivoted rail section,

showing more particularly the construction of a guard to be described.

lo the accompanying drawings. we have shown our invention as applied to a main track 1 and a siding 2, thev former comprising a continuous rail and a rail 4: parallel therewith and having a gap 5 a portion of said track 4 being "extended. laterally at an angle to provide one rail 6 of the siding 2, the remaining rail? of said siding having a gap 8.

By reference to Figs. 1 and 2, it Will be seen that the rails 4- and 7 each terminate in a switch tongue 9, said tongues being pivotally connected to an operating rod 10 which may be shifted laterally by any suitable means such as a lever 11. By the construction above set forth, it will be seen that the rails 4 and 7 lie in intersecting planes and that the ends of said rails as Well as the adjacent ends of the switch tongues 9 are rigidly secured to a solid base plate 12, the latter being rigidly supported upon certain of the cross ties 13 and having a'central bearing recess H- in its upper portion, said recess being of substantially cone-shape and having a bore 15 passing therefrom thfough the lower portion of said base plate.

The bearing opening 15 is provided for the reception of a substantially cone-shaped pivot member 16, the latter having a depending shank 17 which. is rotatably mounted in the opening 15 and which receives a washer 18 and nut 19 on its lower end. It is to the bearing member 16 that a pivoted rail section QUis rigidly secured in any suitable manner as by machine bolts 21, said rail section 20 being of suii'icicnt length to entirely bridge the gaps 5 and 8 when swung in the prope iirection.

For the purpose of swinging the rail section 20 simultaneously uvith the switch tongues 9, we provide said section with a laterally extending operating rod 22 which is pivoted at- 23 to a rather long arm 24 of a bell crank lever, the latter being pivoted at 25 to one of the tics 13 and having its co1nparatively short arm 3 20 extending out Wardly from said pivot and pivotally connected at 27 to a longitudinal operating rod 28, the latter being pivoted at 52$) to one arm; of a bell crank lever 3lL3vhLch is pivoted to one of the ties 13 and. whose remaining arm is pivotelly united et 31 to one end of the transverse switch operating bar 10. The proportioning of the parts so far described, is such as to ellovv the proper movement of the pivoted reil section 20 when the switch tongues 9 are operated by the rod or her 10.

Although the pivotal support for the rail section 20 provides a rather rigid mounting therefor, We have found it expedient to provide specially, constructed means for preventing seid section from tilting, said means being in the form of bars 32, a pair of which projects laterally from each end portion of said rail section, the outer ends of said bars being formed into hooks 33 whose bills open inwardly and are adapted to engage the parallel edges of the base plate 12 when the section 20 stands in either oneoi' its adjusted positions. By this means, it will be seen that any possible tilting, on the part of the rail section 20, will be prevented.

As positive means for preventing excessive movement of the pivoted section 20 in either direction, we have provided a number of angular stops 34: which are carried rigidly by the bed plate 12, said stops contactin with the sides of said section and not on y acting as stops but servin to still further brace the some against tilting.

In connection with the features so far described, we preferably provide a pair of guard rails 35, one of said rails being disposed adjacent the track 3 while one is located directly inside the rail 6 of the sidin It will therefore be seen that lateral shifting on the part of the trucks of a train, is prevented since the wheel flanges of said trucks are limited against lateral or trans verse movement by said guard rails, thus preventing undue lateral pressure from being exerted upon the pivoted rail section Eli From the foregoing description, taken in. connection with the accompanying drewings, it will be seen that we have produced an extremely ellicient switch yet one which will be highly oiiicicnt and positive in operation.

By reference, more purticulitrly to Figs. 1 and 2, it will be seen that the inner ends of the switch tongues 9 as well as the adiocent ends of the rails 4 and 5 are exposed at times. It is a well known fact that brelce beams often become loosened from their supports upon rolling stock and are there fore drawn along the rails or the track. If these beams should come in contact with an immovable object, the result would on cloubtedly be a severe accident. It is to overcome this diiiiculty thatwe have provided the following means whereby a dra ging brake beam will be gradually move up wardly and thus prevented from forcibly striking the ends of the tongues 9 on the adjacent ends of the rails 4 and 5. Said inee eve' set mentioned means is here shown in the erm of pair of laterally extending arms (3 which are rigidly secured to the rail section 20 and chose outer ends are deflected in such men" t to position. then'i dfllllil" cent certain when the switch is one pos on. it will ore Elia) should a dragging some in. cc Jar one oi the arms the fornuition oi the latter will accurutely raise said been and allow the sums to continue to slide upon the rain; of the truck.

We deem this feuturc of our invention extremely important since, as above suggested serious accidents may be averted y this simple yet eflicient'means.

We have described our invention with con siderable ininutcncss but we do not wish to be limited to details of construction other than those amplified in the A pended claims.
